Congratulations op, i must say this is really something good start up for earning bitcoin. It sounds like, op have trust enough on bitcoin, and thats why he agreed to go for bitcoin as payment even after bad market condition, which is wise move. i think thus you Should try to take others payment with bitcoin. Generally you need to expenses for livelihood but if you hold then rest of available dollar with bitcoin, could be big achievement for you
I think being paid in bitcoin is already a good start to invest in bitcoin especially if you can hold it for years as it could mean bigger profits. But the fact that 1 bitcoin is 100x valuable than fiat, i guess that's already a big advantage for us regardless whether it has lower or higher value for now due to its volatility. In my country, a single bitcoin could even buy a new house or a new car, that's how expensive it is. But maybe for now you may get paid in a small portion of bitcoin but once it will be compounded, it will still create a huge value in the long run. So congrats OP, your efforts are now well compensated.
